Port real clojure.pprint (pretty-printer + cl-format)

Browse source

Replace the 33-line pprint shim with a column-aware pretty printer and a
Common Lisp cl-format engine, ported from the ClojureScript implementation
(no STM — atom-backed fields) and adapted to JVM-Clojure interop. Provides
pprint/write/write-out/with-pprint-dispatch/formatter-out/cl-format and
simple/code dispatch.

core print routes column-aware into an active pretty-writer via a __write
hook (suppressed inside with-out-str captures); PrintWriter host class
forwards into the wrapped writer. Re-mint: pprint is baked into the seed.

Unblocks clojure.data.json/pprint (its pretty-printing test passes).
Directives ~R/~P/~C/~F/~E/~G/~$/~(~) not ported (unused by the targets).

make test + shakesmoke green, 0 new divergences, selfhost holds.
